Around the time of World War II, Mead’s personal and professional lives changed dramatically. She divorced Reo Fortune to marry her third husband, Gregory Bateson. She gave birth to a daughter, Mary Catherine Bateson. She turned her anthropological lens on her own culture for the book And Keep Your Powder Dry, part of a larger effort to galvanize Americans for the war effort. Mead’s religiosity was attenuated in this period, for two reasons. One, Bateson, an atheist, did not want their daughter to be indoctrinated, and Mead complied. Two, Mead believed that the challenge of fascism called for a broadly ethical, humanistic response, in which religious narrowness—especially, the alliance of religion and nationalism—could be dangerous.
